Specification of Letters Patent.

Patented July 28, 1908.

Application filed February 13, 1907. Serial No. 357,129.

To all whom it may concern:

Be it known that I, CHARLES L, DYK, a citizen of the United States, residing at Orangev City, in the county of Sioux and State of Iowa, have `invented a certain new and useful Manure-Spreader, of which the following is a specification. j

The object of my invention is to providel a 'manure spreader of simple, durable and inexpensive construction in which the spreading cylinder is supported on hangers extended downwardly and rearwardly from the rear of the wagon body and yieldingly held towardthe 4wagon body by springs so that in the event that a large object should be moved toward the rear of the wagon body, the cylinder will swing rearwardly and permit it to pass without danger of breaking-the Figure 1 shows a side elevation of a ma- :mire spreader body having my in; provements applied thereto. Fig. 2 shows a rear elevation of same. Fig. 3 shows a dftail, perspective view of a pair cylinder terri-gh embodying my invention. Fig. el shows a detail, plan view of the clutch device for throwing the driving chain in and out of gear. Fig. 5

shows a detail, perspective view of the point of'one of the cylinder teeth, and Fig. 6 shows an edV e view of same. l n

Re erring to the accompanying drawings,

l have used the reference numeral 10 to in-` dicate the body of the manure spreader. 11 indicates an apron of the ordinary kind de- Signed to convey materialwithin thebody to the rear end thereof. The'particular construction of the apron forms no part of my present invention and is, therefore, not illustrated or described in detail.

Mounted upon the rear of the wagon box are two brackets 12 tapered toward thel bottom of the wagon box and having at their upper ends bearings 13 to support the stationary-shaft 14, which shaft is provided with a sprocket wheel 16 rotatable thereon.

A sprocket wheel 17 is fixed to' one of the supporting axles 18 of the wagon and a chain 19 connects said sprocket wheels. A chair. tightener 2O of the ordinary type is provided for said chain and attached to the wagon box.

'Mounted upon the shaft 14 are.two hangers 21 extended downwardly and rearwardly and provided with bearings 22 at their lower ends in which a rotatable shaft 23 is mounted. Fixed to this shaft is a spreading cylinder, comprising two disks 24 and longitudinal bars 25 provided with teeth, hereinafter more fully described. Fixed' to oneu end of the shaft 23 is a sprocket wheel 2,6 for drining the cylinder. It is connected by a sprocket chain 27 with a sprocket wheel 28 loosely mounted on the sha-ft 14.

l have provided for throwingthe sprocket wheel 28 in and'out of gear, as follows: On' the hub of the sprocket wheel 16 is a clutch member 29 and on the hub of the sprocket Awheel 28 is a clutch member 30. A bell crank lever 31 is connected to the clutch member 3() by which it may be moved into or out of engagement with the clutch inember 29. The bell crank lever 31 is controlled by means of a rod 32 connected with the lever '33 provided with a spring actuated pawl 34 to engage a sector' 35. A chain tightener 36 of ordinary construction is provided for the chain 27 and is adjustably connected with the adjacent hanger 21.

I have provided for yieldingly holding the cylinder toward the rear end of the wagon body by means of coil springs 37 connected to said hangers and to the adjacent sides of the adjacent body. The movement of the hangers toward the adjacent body is limited by tlie stops 38 fixed to the brackets 12 and arranged to engage the hangers.

By the arrangement of the driving devices for the cylinder, it is obvious that the forward portion of the cylinder will move down wardly. It is, therefore, desirable that means be provided for preventing material from the wagon body passing on top of the cylinder. I have, therefore, provided two brackets 39 fixed on top of the brackets 12 and supporting a transverse bar 40. On this vbar is a number of'spring rods 41 extended l' downwardly Within the Wagon body to a4 point adjacent to the top of the cylinder to prevent the contents. of the Wagon body from dropping on top of the cylinder.

'l have provided improved spring teeth for I thespreading cylinder as follows: T he teeth are formed in pairs, each pair being formed of a single piece of spring inetal'rod. The central portion of each piece is formed into a loop e2 designed to receive a bolt 43 and attaching the pair of teeth to the bars 25.

Beyond the loop e2, the rod extends out- Wardly'in opposite directions at 44. At the ends of the parts ist are the coils 45 to env c er, as clearly shown in Fig. l.

In practical use and assuming that the I spreader is being advanced over a field, the

material Within the wagon body is carried by the apron to the rear end thereof and disl charged toward the spreading cylinder. This cylinder is being rotated in a direction causing the teeth adjacent to the Wagon body to move downwardly, thus tearing loose the particles of the material and discharging e them upon the ground. ln the event that lthe apron should feed the material very rapidly, the springs 37 will yield and permit the cylinder to swing rearwardly far enough to permit the excessive quantity of material to e pass through Without danger of injuring the spreading cylinder o'r in the event that a small particles.

hard lor solid object should be contained Within the Wagon body, it will when striking thev cylinder cause the cylinder to swing rearwardly and permit the object to drop Without danger of breakin the cylinder or the teeth thereof. Norma ly the teeth on the cylinder are so close to the rear end of the' Wagon thatv no appreciable quantity of the material may pass from the Wagon Without being engaged by the teeth and torn into A By the arrangement of sprocket gear, it is obvious that the cylinder will be operated equally Well when a-t any position of its limit of movement relative to the wagon body. v l

Having thus described my invention, what l claim and desire to secure by Letters Patent of the United States, therefor is.--

. 1. ln a manure spreader, the combination of a Wagon body, hangers pivotally connected With the Wagon body and extended downwardly at the rear thereof, a spreading cylinder `sup orted by the said hangers, a s haft f mounte .atthe pivotal point of the hangers, l

and a gearing device mounted on the shaft and connected with the cylinder for driving the latter.

i 2. ln a manure spreader', the combination of a Wagon body, hangers pivotally connected With the Wagon body and extended downwardly at the rear thereof, a spreading cylinder supported by the said hangers, a shaft l mounted at 'the pivotal point ofthe hangers,

a gearing device mounted on the shaft and connected Awith the cylinder for driving the latter and a clutch for throwing the cylinder in and out of gear.

3. ln a manure spreader, the combination of a Wagon body, hangers pivotally connected with the Wagon body and extended downwardly at the rear thereof, a spreading cylinder supported by the said hangers, a shaft mounted at the pivotalpoint of the hangers, and a gearing device mounted on the siaft and connected With the cylinder' for driving cylinder toward the Wagonl body and a stop for limiting the movement ofthe cylinder toward the Wagon body.

5. In a manure spreader, the combination I With a Wagon body, of brackets secured to the rear thereof', a shaft supported in said brackets, a pair of hangers mounted on the shaft and extended downwardly at the rear of the Wagon body, a spreading cylinder supported by said hangers, a sprocket gearing operatively mounted 0n the said shaft and 'connected with the said spreading cylinder, a

manually controlled clutch deviceforithrorving the cylinder in or out of gear, a bar supported above the rear of the Wagon body, a number of spring rods vfil/red thereto 'and eX- tendeddownwardly in advance of the cylinder, a spring for yieldingly holding the cylinder toward the wagon body and a stopy for-` limiting the movement of the cylinder' toward the Wagon body.

6. In a devicev of the class described, acyl-l inder tooth having its outer end oval in cross section with its edges ta ered toward a point and with one side straig it and the other beveled'toward the point.

7. ln 'a manure spreader, the combination of a Wagon body, hangers at the ,rear of the Wagon body capable of movement toward and from the Wagon body, a spreading cylinder rotatably mounted in said hangers, and a spring for yieldingly holding the hangers toward the Wagon body.
